The mean duration of symptoms was 3. Septic loosening, subtrochanteric fracture, and acetabular fracture at time of primary surgery that did not heal were the reasons for the 3 remaining revisions.

A strict application of indications is necessary, which is supported by the results of Chun et al.

Component migration was assessed by measuring inclination angle, femoral-stem angle, and component-lateral cortex ratio. As a result of metal wear and extensive necrosis of the femoral head, short-stemmed solutions for patients with osteonecrosis of the femoral head may be considered. J Am Acad Orthop Surg.

The extent of necrosis was evaluated with the use of magnetic resonance imaging.


After the average follow-up period of 88 months, there were no complications requiring additional surgical treatment and the clinical state of patients was excellent. The effect of surgical approach on blood flow to the femoral head during resurfacing.

Surgical technique All operations were performed with the patient in the lateral position and through a lateral approach Hardinge approach and all patients received antibiotic prophylaxis at the time of induction of anesthesia as well as 2 postoperative doses of antibiotics. Or filter your current search. The small number of patients is related to the strict inclusion criteria.

A Hip resurfacing; inclination angle, component-lateral cortex ratio, B Hip resurfacing; stem shaft angle. The radiographic analysis showed no component migration jacej collapse. Blood supply to the femoral head is much better preserved during an anterolateral approach [ 2627 ]. The mean follow-up was Europe PMC requires Javascript to function effectively.

Table 3 Radiographic results, component alignment. All patients were evaluated clinically and radiologically before and 60 months after the operation. Table 2 Clinical results. There were 5 revisions 6.

Level of physical activity was assessed with UCLA activity score prior to surgery and at each postoperative visit up to 3 years after surgery [ 15 ]. Osteonecrosis of the femoral head is caused by impaired vascular supply.
